Started on the cafe this morning… mapping circuits rather than testing… but this is the start of the interesting stuff.
Original 3ph fuse board with HRC cartridge fuses. Later added modern CU with RCD mainswitch, monitoring meter again.
Mix of metal conduit, plastic conduit, surface T&E and MICC…. Sometimes within the same circuit!
Joints in the trunking… including a 100A Henley block to supply the newer CU.
Oversized fuses for size of cable…. All lights on one fuse….
And I’m puzzled about the cable supplying the 3ph cooker. (3 separate fuses, I believe only single phase loads within the cooker itself, however)
The cable isn’t SWA. It’s 5 core (numbered on black) with a braided outer and transparent plastic sheath. I should have taken a better photo.
Come across it before on agricultural for grain dryer motor controls etc.
Isolated upstream in workshop, 63A MEM switch fuse complete with asbestos flash pads.
